Ok thanks Marko. But just to be clear - you could have a key with list
cardinality with multi-properties - that is to say, multiple lists, right?
Like for example, if the <V> in Vertex.property was a List? I assume this
would be quite an unusual case and I'm not sure why anyone would want to do
it, but it still needs to be supported?
Vertex v = ...
v.property(Cardinality.list, "prop", Arrays.asList("a", "b", "c"));
v.property(Cardinality.list, "prop", Arrays.asList("d", "e", "f"));
